I have the speakjet connected to the arduino. I can put the speakjet in demo mode and hear all the jibberish. If I put it in normal mode, I cannot get it to say anything. I can reset the chip and hear "ready" but it will not say what I send serial. I was worried the baud rate was somehow changed so I did the sonar ping thing and you can see that in my commented out code below. I know pin 7 is sending serial data to rcx but only by looking at a volt meter dip during the serial send. I don't have a scope to actually look at the data stream. I do not know what I am doing wrong....Some of the code below is "deparation" coding attempts since nothing is working.
